Product Description

Product Description
High dimensional accuracy. The cold-rolled coil processing production line cuts the steel in a cold state. The cutting accuracy of the cross-cut products can reach ±0.3mm, and the length-cut products can reach ±0.03mm. It can be precisely processed according to the requirements of customers.
Eliminate the internal stress of steel. The flat plate is mechanically opened in the state of cold rolling, which can greatly eliminate the internal stress of the coil. The stress relief is generally 60%-80%. The elimination of internal stress greatly improves the mechanical properties of the steel plate.

Our AdvantagesHigh Strength
The hot-rolled steel plate products produced by Zhengde have excellent properties such as high strength, good toughness, easy processing and good weldability, so they are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels.Adequate inventory
Spot inventory of steel plates with various material properties: ordinary carbon structural steel plates, low alloy steel plates, alloy steel plates, wear-resistant steel plates, steel plates for cold forming, structural steel plates, automotive structural steel plates, steel plates for corrosion-resistant structures, mechanical structures Steel plates, steel plates for welded gas cylinders and pressure vessels, steel plates for pipelines, etc.Attention to detail
The surface quality is good. Compared with ordinary hot-rolled sheets, Zhengde hot-rolled sheets have removed the surface oxide scale, improved the surface quality of steel, and are convenient for welding, oiling and painting.
The dimensional accuracy is high, and after leveling, the plate shape can be changed to a certain extent, thereby reducing the deviation of unevenness. Improved surface finish for enhanced appearanceProvide deep processing
Relying on Zhengde's sufficient steel plate resources, it reduces the pressure on customers' inventory. It can be cut according to drawings, or directly cut into graphics required by customers, such as circles, rectangles, flanges, bearing housings, rolling mill racks, and rolling mill arches, etc. The cutting precision is high. , the incision is smooth and tidy, and the machining allowance is small.
Quality first: production and inspection in strict accordance with production standards;
Price advantage: discounts based on real market prices;
Transaction security: There will be no loss of customer funds;
After-sales guarantee: the customer's problem is our problem;
Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.Detailed Photos
